Hi all, I can't figure out what the next step is on a problem. The problem is:
A car moving at a speed of 35 m/s enters a curve that describes a quarter turn of radius 130 m. The driver gently applies the brakes, giving a constant tangential deceleration of magnitude 1.2 m/s^2. Just...
Ok, I figured it out, thanks. Basically for T1 what I was doing wrong in the equation T = m (g-a) was taking 9.81-2.31 instead of adding them together. Then I was able to figure out that T3 was 8 (9.81-2.31).
I have a couple questions that I can't figure out regarding the following question. The picture pertains to the question.

Three blocks of mass m1 = 4 kg, m2 = 5 kg and m3 = 8 kg are connected by strings which pass over two ideal pulleys as...
For #2 I had something similar to what rmarkatos said, but I think I skipped a step and therefore got the wrong answer.
For #3 I'm not really sure. We had a mass in an elevator where the rope could handle a certain amount of tension (60N) before it broke and we had to find the maximum...
I have a few questions on some homework I'm trying to do:
1) A 3.5 kg flowerpot drops from a tall building. The initial speed of the pot is zero, and you may neglect air resistance.
After the pot has fallen 33 m, it enters a viscous liquid, which brings it to rest over a distance of 1.5...
